Consumer review (reevoo.com)

Lenovo B51-80 80LM

 

Good performance, not heavy. An excellent value for money choice.

Laptop's plastic material is cheap. As a result the keyboard-build is not very robust and might flex after extensive use. If you have a peripheral keyboard/mouse, then this won't be a problem.

Lenovo B51-80 80LM

 

Has left and right cursor buttons, something that most new laptops no longer have.

This isn't a bad point about the unit, but I'm still getting used to Windows 10 as my last operating system was Windows XP!!

The laptop is brilliant for the price. Speedy start up and applications open quickly.

There is a slight design flaw to the laptop which creates a sharp edge to the front of the laptop. But find this only is a problem when using the laptop in a bad position on sofa and not at the desk.

Lenovo B51-80 80LM

 

Once it gets going it is quite a powerful and capable machine. Full size keyboard is nice. Battery life is ok, about 3-4 hours in my experience. Good selection of ports. Multi-touch keyboard is pretty useful. Fast start up. Very quiet.

Although it is lighter than my previous 15-inch laptop, it is overall bigger and less portable due to the bigger keyboard. Quite a bit of bloatware needs to be removed before using it. 1366x768 resolution screen isn't the best looking. DVD Drive is...
